To a iii/mm Cit nnm-y concern:

Be .i known,that.., Emmnn Bivizeiini'iman, a citizen of: the vUnitedStates, residing at Portsniouth, in the county of Roeltingham and Stateogl, New Jalahiqgshire, have inan automatic severingdeevi'ee andmechanism whereby when the paper .on't-he .inal'te-up roll, (of a .wetpaper machine shall have arrivedut a certain thickness, the saidmechanism willbe automatically operated to sever the paper on themake-up rollentirely there-- 'aeross the paper thus severed .l'eing.then liin-v n'iediately removed from the make uproll by theoperator and the automatic mechanism returning to its,ti1'st position,in order to repeat the severing operation.

The invention contemplates anadjustable feature whereby the severinggniechanism may be lOPQYdtQd when the paper arrives any predeterminedthickness upon theimakeup roll.

'The mechanism of this iinventioiris "further provided with vsafetymeans whereby it any unforeseen condition should arise in the operationof the mechanism, whereby undue strain may be brought to bear upon nuyoi the parts thereof, the satiety means will operate to prevent breakageor ,injury to any o'lhthe min ol the mechanism.

The wet paper machine to which this inxentionis particularly athipted isw all known to those skilled in the artand embodies therein amake-uproll, a s;uide roll and a belt which passes between the makeuproll out in the claims and in the Combination ot'.

the same with a wet paper machine.

- out (the several views of the drawings.

In the drawings, 10 isi'the liraine ofvthei nachine comprising two sidestandards 11 and 12 in which isslidahly mounted (a frame 13 co iprisingtwo slides 14. and 15 ,slidahly mount-ed irespectively in the standardsll and .12 and rigidly fastened.together by a cross beam 16.- l? is the,n' ake up roll o'tza wet paper inimhine, 'WlllCll is fastened to ,ashaft :18 rotatablymounted in hearings in the slides i1 1: and 15 of theslide frame 13. 19 is a cutter shaft also rotatably mounted at itsopposite ends in "the slides .14 and 15 l ormingla part of the slideframe The cutter snattt- 119 has a flange 20 extending lv therefrombeneath the make-up roll ,1?

and on to a guide roll 27, the paper pulp loo 28 on the belt thus beingtransferred to the make-up roll 17. Rotary motion is imparted to themake-up roll by the belt and thus the. gears 23 and will be rotated inthe direction indicated by the arrows thereon. The gear 23 has a hub 29thereon provided with a recess 30 in its outer edge and said gear andhub constitute one member of a clutch 31. The other member 32 of theclutch is splined to the cutter shaft 19 and is slidable longitudinallythereon. The member 32 has a projection or a tooth 33 thereon adapted toengage the recess 30 in the hub 29 when moved longitudinally of theshaft 19, or toward the left Figure 1. The clutch member 32 is movedlongitudinally of the shaft to cause the same to engage the clutchmember 29 by a shifting lever 34 which is pivoted at to a bracket 36forming a part of the slide 15.

The lever 34 is bifurcated at its lower end and embodies at said lowerend two arms 37 and 38 to which is pivotally mounted, by trunnions 39and 40, a two-part segmental ring 41 which has a groove 42 engaged by aflange 42 on the periphery of the clutch member 32. It will thus be seenthat if the upper end of the lever 34 is rocked toward the right Figure1, the clutch member 32 will be thrown into engagement with the clutchmember 29 and vice versa. The shifting lever 34 is moved at its upperend toward the right, Figure 1, to throw the member 32 into engagementwith the member 29 by mechanism actuated by the movement of the make-uproll 17 upwardly, which is caused by the paper pulp 28 being depositedthereon by the belt 25. This mechanism will now be described.

When the make-up roll is moved upwardly as hereinbefore described, theframe 13 will also move upwardly and a hardened plate 43 will engage ascrew 44 which has screw-threaded engagement with a lever 45 pivoted at46 to the lower end of a vertical rod 47 which is slidably mounted in ahraclcet 48. A lever 49 is pivoted at 50 to a link 51, which in turn ispivoted at 52 to a bracket 53 fastened to a cross beam 54 which forms apart of the frame of the machine and is rigidly fastened at its oppositeends to the side frames 11 and 12. The lever 49 is connected by a pin 55to the rod 47 and has a counter-weight 56 fastened to its outer end. Itwill be seen that any undue resistance to the upward movement of thelever 45, when the same is engaged by the plate 43, forming a part ofthe slide frame 13, will cause the pivot 46 and rod 47 to be movedupwardly tipping the lever 49 upon its pivot 50.

The end of the lever 45, opposite that to the pivot 46, has dependingtherefrom an arm 57 which is connected to said lever by a pin 58, and atthe lower end of the arm 57 a spring-actuated latch 59 is slidablymounted. The outer end of said latch normally projects beneath aprojection 60 rigidly fastened to a spring-actuated stop 61, which isslidably mounted in an auxiliary frame 62 which is fastened to the crossbeam 54 of the frame of the machine. The lower end of thespring-actuated stop 61 normally projects into a notch 63 in aspring-actuated member 64. The spring-actuated member 64 is connected bya link 65 to the upper end of the shifting lever 34 by a pin 66. Thespring-actuated member 64 is slidably mounted in the auxiliary frame 62and projects into a casing 67, which is provided with a chamber 68containing a spring 69. One end of the spring 69 bears against a collar70 having screw-threaded engagement with the spring-actuated member 64.The other end of said spring bears against one end of the chamber 68.

The casing 67 is pivotally connected at 71 to the vertical arm of thebell-crank lever 72, pivoted at 73 to the auxiliary frame 62. Thehorizontal arm 74 of said bell-crank lever is pivotally connected at 75to the latch carrying arm 57. A bell-crank lever 76 is pivoted at 77 tothe auxiliary frame 62 and the outer end of the horizontal. arm 7 6 isprovided With an inclined surface 78 which is engaged, when the partsare in the relative positions illustrated in Fig. 5, by a rectangularprojection 79 fast to the member 64. The vertical arm of the bell-cranklever 76 has a rocker plate 80 pivoted thereto at 81. This rocker platenormally bears against a shoulder 82 on the bell-c 'ank lever 76.

The clutch member 32 is thrown out of engagement with the clutch member29 by by a pair of contact members 83 and 84 which are pivoted at 85 and86respectively to the clutch member 29 and to the lower end of theshifting lever 34. Normally these contact members are in the relativepositions illustrated in Fig. 9 and are held in such positions bysprings 87 and 88 respectively. The contact member 83 has a segmentalarm 89 thereon and a stop arm 90. The contact member 84 has a segmentalarm 91 and a stop arm 92. The curved contact face 89 of the contactmember 83 is eccentric to its pivot 85 and the curved contact face 91 ofthe contact member 84 is eccentric to its pivot 86.

\Vhen the parts are in the positions illustrated in Fig. 9, the spring87, holds one end 93 of the segn'iental arm 89 against the face 94 of aplate 95, which is fastened by screws 96 to the clutch member 29 andforms a part thereof. At the same time the end 97 of the segmental arm91 abuts against a stop face 98 on the lower end of the lever 34-, andis held thereagainst by the spring 88.

.Vhen the contacts 83 and 84 are in the relative positions illustratedin; 11 then the stop arm 90 abuts against zthe lace of -the plate 95 andthe-stoparm 92abuts against the stop face 99,- as=illustrated iii-Fig;11, i

The gene 'al operation of the .qneclian-ism hereinbetore specificallydescribed is 13w follows; Assuming the parts to iboin therrelathepositions. illustrated: inthe drawings, Figs. 1, 2, 3;. 4-, ti and!) Asthe paper pulp board mountsup on then'iake-up 'roll 17, the said make-uproll will be moved awayifrom the guide roll 27 and will earry with it,throughitsshaft 18, the slide frame 13 and will therefore move upwardlyat; the same time, the gear-2 11;, cutter shaft 19 and {its outtenblade21, the gear 23' and clutchuncn' ber 29, of which it .torms a part, theclutch member 32 and the shittinglever 34-, link--65,

When the latch 59 is moved from the position illustrated in Fig. 7 tothat illustrated in Fig. 8, it will be pushed out from under the plate60 forming a part of the springactuated stop 61 and this will releasethe stop 61, which will then be forced down wardly by its spring 61,Fig. 4, and assume its original position as illustrated in Fig. 4, withthe lower end of the stop 61 projecting into the notch 63 on thespring-actuated member 6%, and thus locking said spring actuated memberagainst movement toward the right, Fig. 6, and consequently the shiftinglever 34: and the clutch member 32 and the contact member 84 will belocked in the respective positions illustrated in Figs. 1, 4t, 6 and 9.

When the paper board has been removed from the make-up roll by theoperator, as hereinbefore described, the makeup roll 17 will movedownwardly to contact with the belt 25 and this will carry the slideframe 13 downwardly together with the cutter shaft and cutter and otherparts mounted thereon, whereupon the latch 59 will be lowered from theposition illustrated in Fig. 8 to the position illustrated in Fig. 6 andwill be forced by its spring 59 toward the right and beneath the rockerplate and the projection 60 on the stop rod 61 and the parts are then inthe relative positions illustrated in Figure 1 ready to again performthe operation hereinljiefore described and. sever another section ofpaper board upon the makeup roll 17.

If any obstruction, or if for any cause, undue opposition to themovement upwardly of the lever at the right hand end thereof, shouldarise, the lever t5 would then be moved upwardly at its left hand end bythe slide frame 13 and this it would be enabled to do by reason of therod 47 sliding up wardly in the bracket 48 and rocking the lever 49 onits pivot 50. W hen the obstruction, or other cause, has been removed,then the weight 56 will force the rod 47 down wardly and the parts willassume the rela tive positions illustrated in Figure 1.

The construction last described prevents breakage or injury to thedifferent parts of the mechanism when any undue strain is brought tobear thereon for any reason.

It will be seen that by adjusting the screw 44 downwardly, the mechanismhereinbefore described will be operated sooner than when the screw statis adj ustcd upwardly and therefore, the slide 13 would have to travel aless distance before the cutter is operated to sever the paper board inone instance, than in the other, thus the thickness of the paper boardwhich is removed from the make-up roll may be predetermined by adjustingthe screw 44.

The clutch mechanism per se, while having been fully described andillustrated in the foregoing specification and in the drawings, in orderto disclose one form of clutch, whereby the severing of the paper boardmay be accomplished, is made the subject matter of a separateapplication filed by me of even date herewith, Serial No. 669,455).
